3-Phase Brushless DC Motor Fans

Data center and server cooling fans demand high energy efficiency and low rotating vibration to achieve thermal requirements and operating performance. Delta's 3-Phase Brushless DC Motor Fans, powered by 3-Phase motors, provide smoother transition between slots compared to single-phase motor fans. The benefits of 3-Phase motors include low cogging torque, low vibration disturbance, smooth rotational torque, and high power efficiency.

There are 3 core technoligies implemented with the Delta 3-Phase Brushless DC motor fans, blade design, advanced motors and electrical drives, and also an enhanced structure to prevent vibration.

Features & Benefits:

  • Optimized blade design for high efficiency
    • Delta is constantly studying the CFD analysis and Delta's own airflow section software. We assess every aspect of the fan's airflow path to minimize the vortex which delivers a more efficient product. Delta continues to develop innovative cooling solutions in optimizing our fan's blade design to increase the aerodynamics for maximum energy efficiency and lower vibration.

     

  • Powered by 3-Phase motors and advanced electrical drives
    • Well-known operational control circuit for motor driving availability can serve to evaluate the motor back electromotive force impact of efficiency and vibration. Delta develops precisely 3 phase motor driving technology to control fan rotation with minimum back electromotive and switching noise.

  • Enhanced structure to achieve low vibration
    • Delta's axial fans and blowers for automotive applications come in every size and power level, and can be customized to fit and perform at maximum efficiency in any vehicle. You'll find Delta fans, blowers and electronic devices inside most of the world's top automotive brands. From the headlights to the interior, automotive applications include seat ventilation, HVAC blowers, air purifiers, and even fans for mobile entertainment systems. Cars and trucks have to operate under the harshest conditions, and Delta cooling solutions are built to withstand the same extreme temperatures, shock and moisture. Features and benefits include:
      • Higher air pressure and air flow
      • Lower power consumption and reduced noise output
      • Delta's world-class support team for customized design
